Nor'Easter Continues to Bring Heavy Rain and Coastal Impacts; Nolo Continues to Impact Hawaii

The nor’easter will weaken tonight, easing beach conditions and coastal flooding, though locally heavy rain will continue in parts of the Mid-Atlantic and New England into Monday. Hurricane Nolo continues to bring strong winds and large waves to Hawaii. A multi-day rain event will return to the Four Corners region Monday and expand to the south-central U.S. by midweek.

A Coastal Flood Warning is in effect for the Upper Keys. A Coastal Flood Advisory is in effect for the Lower and Middle Keys. In the Upper Keys, numerous roads may be closed. Low lying property including homes, businesses and some critical infrastructure will be inundated. Some shoreline erosion will occur. In the Lower and Middle Keys, saltwater flooding of low elevation streets and lots is expected. Some storm drains will overflow, and some seawalls and docks will be overtopped. Boaters should expect less clearance under fixed bridges. Motorists should remember that persistent puddles around the times of high tide are almost certain to contain a mix of saltwater. For more information on coastal flooding, refer to www.weather.gov/key/coastal_flooding
A large and potent Nor'Easter off the New Jersey/New York coastlines is causing the Gulfstream to slowly back up (think of it like a traffic jam on the 18-mile stretch). As the Gulfstream backs up, the effects will reach the Keys in the form of continued coastal flooding. Unfortunately, the Florida Keys will continue to see high tides of 1-1.5 feet above normal predicted tides at times.
